This is a fix for issue #52

Removes the grammar<->NSTextView KVO.
Gets rid of enable/disable state for textView since it breaks undo history and I don't think it actually adds any value.
Now uses [self.textView string] as the authoritative state of the NSTextView (grammar).

After this change undo history is maintained after generate or File->Save.

FYI, FIxed a problem where loading the saved file did not work. I've been using this for several days not and seems to be working really well.
